Here is how to begin your data science journey:

1. Buy a book on modern data science, avoid statistics textbooks re-labeled as data science like plague: they will lead you to nowhere. Any public-domain stuff that's been invented 50 years ago will lead to a job that will eventually be replaced by a robot - we are working on this to make it happen. If you have an analytic background, my book…

Here I describe a case study: a solution based on high-level data science. By high level, I mean data science not done by statisticians, but by decision makers accessing, digging into, and understanding summary (dashboard) data to quickly make a business decision with immediate financial impact. There is also a section on smart imputation techniques, with patentable, open intellectual property that we created after investigating this problem.

This article is articulated in three…

Three thoughts this time, for our first edition of Thoughts of the Week.

Thought #1

An estimate that is slightly biased but robust, model-independent, easy to compute, and easy to interpret, is better than one that is a non-biased, difficult to compute, mysterious, or not robust. That's one of the differences between data science and statistics.

Thought #2

Learning how to code, especially SQL, should be the last step in…

The case study presented here - including root cause analysis and solution - was performed for a digital publisher. It offers a different perspective on what data scientists are capable of. The expert involved here is not a coder, certainly not a production guy, yet is able to leverage his business acumen and domain expertise to

• Imagine dozens of scenarios and rank them by chance of occurring
• Get silo-ed data from various departments (finance, sales, marketing, product,…

In this article, I share some of my unusual views about big data and data science. My next article will be about new trends in data science.

Big data is necessary in more applications than people think

And used with success. It includes

• Scoring transactions (credit card purchases) in real time
• Automated piloting
• Monitoring car traffic (sending alerts, finding optimum routes). Same with planes.
• Digital…

These tips are provided by Dr Granville, who brings 20 years of varied data-intensive experience working with successful start-ups, small companies across various industries, and eBay, Visa, Microsoft, GE and Wells Fargo.

A few websites catering to analytics and data science professionals have experienced tremendous growth recently. Organizations such as INFORMS or AMSTAT have seen their traffic explode, targeting high school students to join the ranks of data scientists. Niche publishers providing high quality, actionable content - and run by true data scientists rather than journalists - have also seen spectacular growth.…
